I trust very few "sources", especially these days. And even more especially, in the middle of a war between two former USSR states that have deep histories in manipulating public opinion and weaponizing that against their adversaries.

> weaponizing that against their adversaries

I understand your skepticism, but here is an interview from April 2025 with the founder of VYRIY, a Ukrainian drone company: https://militarnyi.com/en/news/vyriy-founder-compares-accura... According to him, Russian drones are far superior. "In terms of [Ukrainian drone vs Russian drone] quality, well, like 10% vs. 80%. It’s not even comparable,” Oleksii Babenko sums up.

That article suggests that the difference is due to economics & possibly intended use, not technological advances.

Manufacturing is a technology.

Again, I don’t trust sources that are random quotes on the interwebs during a conflict where people are dying (or corporate PR speak) but maybe that’s a me problem?
